Diagnosis of fuel system: Notes

P2187/P2189, P2188/P2190, P2177/P2179, P2178/P2180 

This diagnosis is able to analyze up to two fuel systems, each with its own fault paths. In case of a stereo system with two fuel systems, each fuel system is monitored separately but all in the same way._

The detailed error paths of this diagnosis are not illuminating the MIL but the general failure path FMAS. The handling of the general failure path FMAS is described in an additional document.
